DG401DYZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG401DYZ-T is a dual single-pole single-throw (SPST) normally open analog switch manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 5V to 34V for single supply or ±5V to ±17V for dual supply configurations. The device features a maximum on-resistance of 45 ohms with a channel-to-channel matching of 3 ohms. Switching times are specified at a maximum of 150ns for turn-on and 100ns for turn-off. Key electrical characteristics include a charge injection of 60pC, off-state leakage current of 500pA, and a crosstalk specification of -90dB at 1MHz. The component is housed in a 16-SOIC package and supports an operating temperature range from -40°C to +85°C.
